IMPROVEMENT IN Boor-TREES.

Specification forming part of Letters Patent No. 177,753, a May .23, 1876;V application filed 4 April 10, 1876.

To all whom it mag/concern: 1

Be it known that I, J AAMES HENRY SAMP- SON, of Paris, Province ot' Ontario, Canada,

have invented a new and Improved Center- Graduating Boot-Tree, of which the following is a specification:

My invention consists of a lever and an adjusting`screw on the Wedge-piece, to be used in combination with the front piece and a series of back pieces Vof different sizes, contrived for stretching o'r treeing the ankle or center and foot piece, making a simple but powerful and eflicient tree. Figure l is a sectional elevation of my 11n- 'proved boot-tree, taken on line w 00, Fig. 2;

and Fig. 2 is a horizontal section taken on line y y, Fig. l.

Similar letters of reference indicate corresponding parts.

A is the front piece, and B the foot-piece, which connect by the shoulders et and the iiange b. AD is the Wedge or slide piece; and E is the back piece, and d the center of the same. The Wedge-piece has a slot, F, down ing it, the nut being worked against the rear of the middle piece D. V

A series of backs with different centers d will be employed for instcps of different heights. Boots are out at the anklev or center, smaller thanthe measure, and treeing is for the purpose of extending thematthntpoint, in order to let the foot go in free. With a low instep the center 'or ankle is low, and with a higl1- I one the reverse; therefore, as the center is on the back, (if'thereis only one back there is only one center for all ankles,) this my plan remedies, for by having a series of backs the tree can accommodate it to any size; but three Vbacks are sufficient for the usual six sizes.

J is an adjusting-screwin the top of the front to expand the leg. v

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with sections A D, of the screw J and lever G, the latter bearin g against the ankle at one end, and a't the 'other oper ated by device H I, as shown and described,

to admit the use of varying backs and insteps.
